title: Frequency of anaemia in patients with systemic lupus erythematosus at tertiary care hospitals.
abstract: OBJECTIVE
  To analyze the frequency and causes of anaemia in systemic lupus erythematosus (SLE) patients attending in department of medicine at tertiary care hospitals.
  
  
  METHODS
  This retrospective, descriptive and analytical study was planned to analyze the frequency and causes of anaemia in SLE patients attending the department of medicine at (MMC) and (LUMHS) hospitals during the period of Jan 2006 to Nov 2008. The criteria used in this study were from the American College of Rheumatology. Investigations recorded were blood complete picture, absolute values, peripheral smear, and reticulocyte count in all patients of anaemia. These investigations were necessary to analyse the cases of anaemia in SLE. All investigations were not done in all cases. Patients with hypochromic microcytic anaemia were advised to have serum iron and ferritin levels, seven patients with macrocytic anaemia were advised to have direct and indirect coomb's test, LFTs, serum LDH, serum B12 and folate levels. Patients with normochromic and normocytic anaemia were considered to have anaemia of chronic disease. Bone marrow aspiration and Hb electrophoresis were done in two patients with anaemia of chronic disease. Thirty adult patients were included in this study. Special proforma were prepared to record the information from case sheets of patients including basic information, symptomatology and laboratory investigations. Severity and various types of anaemias were recorded. Anaemia was graded according to severity, as mild (Hb 10-12 G/dl), Moderate (Hb 8-10 G/dl) and severe (Hb < 8 G/dl). Haemoglobinopathies and other types of anaemias were excluded from study.
  
  
  RESULTS
  Thirty adult diagnosed patients of SLE, were included. Their ages ranged from twenty years to fifty years at time of presentation. The mean age +/- SD (range) was 28 +/- 6.22 (20-50) years and median age was 31 years. Out of thirty patients, twenty seven (90%) were females and three (10%) were males. Twenty eight (93.33%) patients presented with anaemia, 14 (46.66%) patients were of mild anaemia, 8 (26.66%) patients were of moderate grade anaemia and 6 (20%) patients had severe anaemia. Iron deficiency anaemia was found in 9 (30%) patients, 12 (40%) patients had anaemia of chronic disease and 7 (23.33%) patients had haemolytic anaemia, out of theses 7 patients, 5 (16.66%) patients had Coomb's positive haemolytic anaemia. All thirty patients had ANA positive titres > 1:80; and nineteen (63.33%) patients had anti ds DNA positive, titres > 1:10.
  
  
  CONCLUSIONS
  Haematologic abnormalities are common manifestations in patients with SLE. Most patients exhibit anaemia at some point during their disease course.
